A novel channel estimation algorithm applied to UTRA-FDD

Channel estimation is a key step in the initial synchronisation of a RAKE receiver. In this paper we present an algorithm for multipath channel estimation based on an elegant and efficient new technique for resolving the multipath components. The performance of the algorithm is assessed through simulation as part of a RAKE receiver in a fully compliant UTRA-FDD uplink scenario. Test results are presented and compared with those of other channel estimation techniques.
